Rapid estimation of octanol-water partition coefficient for triazole fungicides by MEKC with sodium deoxycholate as surfactant

, 2008
A rapid estimation of octanol-water partition coefficient (log P-ow) was developed for triazole fungicides by micellar electrokinetic chromatography (MEKC). Five standard compounds with known log P-ow values from 2.9 to 4.3 (cyproconazole, bromuconazole,

Electrokinetic Manipulations Combined With Direct and Ambient Ionization Mass Spectrometry

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 244-259, March/April 2026.
ABSTRACT Mass spectrometry (MS) is a powerful analytical technique that typically involves sample preparation and online analytical separation before MS detection. Traditional methods often face bottlenecks in sample preparation and analytical separation, despite the rapid detection capabilities of MS.
